核心交换机配置DHCP服务，这篇文章有详细的步骤和命令

动态主机配置协议DHCP（Dynamic Host Configuration Protocol）是一种用于集中对用户IP地址进行动态管理和配置的技术。 

下面我为大家整理了非常详细的配置步骤和命令，仅供参考学习，如有错误，还望指点指点。 

 一、华为交换机配置DHCP服务 

1、交换机开启dhcp服务 

[Huawei] dhcp enable 

2、配置用户网关，并在接口下开启dhcp全局模式 

[Huawei] interface vlanif 10 

[Huawei-Vlanif10] ip address 192.168.10.254 255.255.255.0 

[Huawei-Vlanif10] dhcp select global 

[Huawei-Vlanif10] quit 

[Huawei] 

3、创建地址池 

[Huawei] ip pool vlan10 

[Huawei-ip-pool-pool1] network 192.168.10.0 mask 255.255.255.0 

[Huawei-ip-pool-pool1] dns-list 114.114.114.114 

[Huawei-ip-pool-pool1] gateway-list 192.168.10.254 

4、保留 192.168.10.1-192.168.10.10 不下发 

[Huawei-ip-pool-pool1] excluded-ip-address 192.168.10.1 192.168.10.10 

[Huawei-ip-pool-pool1] quit 

[Huawei] 

 二、华三交换机配置DHCP服务 

1、交换机开启dhcp服务 

[H3C] dhcp enable 

2、配置用户网关，并在接口下开启dhcp全局模式 

[H3C] interface vlan-interface 10 

[H3C-Vlan-interface10] ip address 192.168.10.254 255.255.255.0 

[H3C-Vlan-interface10] dhcp select server global-pool 

[H3C-Vlan-interface10] quit 

[H3C] 

3、创建地址池 

[H3C] dhcp server ip-pool vlan10 

[SwitchA-dhcp-pool-vlan10] network 192.168.10.0 mask 255.255.255.0 

[SwitchA-dhcp-pool-vlan10] dns-list 114.114.114.114 

[SwitchA-dhcp-pool-vlan10] gateway-list 192.168.10.254 

[SwitchA-dhcp-pool-vlan10] quit 

[H3C] 

4、保留 192.168.10.1-192.168.10.10 不下发 

[H3C] dhcp server forbidden-ip 192.168.10.1 192.168.10.10 

 三、锐捷交换机配置DHCP服务 

1、交换机开启dhcp服务 

Ruijie(config)# service dhcp 

2、创建用户网关（以vlan10为例） 

Ruijie(config)#interface vlan 10 

Ruijie(config-if-VLAN 10)#ip address 192.168.10.254 255.255.255.0 

Ruijie(config-if-VLAN 10)#exit 

Ruijie(config)# 

3、创建地址池 

Ruijie(config)# ip dhcp pool vlan10 

Ruijie(dhcp-config)# network 192.168.10.0 255.255.255.0 

Ruijie(dhcp-config)# dns-server 114.114.114.114 

Ruijie(dhcp-config)# default-router 192.168.10.254 

Ruijie(dhcp-config)# exit 

Ruijie(config)# 

4、保留 192.168.10.1-192.168.10.10 不下发 

Ruijie(config)# ip dhcp excluded-address 192.168.10.1 192.168.10.10
